The Ohio CDL manual describes amber warning light activation at least 200 feet before a stop, while Ohio pupil transportation safety procedures use approximately 300 feet whenever practical. Which approach should an Ohio school bus driver follow?

1. Follow Ohio's pupil transportation procedure and any local route rules, using about 300 feet whenever practical
2. Ignore Ohio procedure because the CDL manual number is always the only rule
3. Use no amber lights unless a police officer is present
4. Choose any distance as long as the stop arm works
